Check The Weather & Find Out How What Flexibility You Have
If at all possible, try to schedule your move for a day when it is not supposed to have any rain or snow falling. If you are renting a truck to move with, find out if you will be able to postpone your rental if the weather is too poor for you to move forward with your move.
You should also make sure that you build some flexibility into your moving dates, so that you can change your moving dates if the weather is poor. Talk to the manager or owner
